conditional representation of logical numbers

2 views (last 30 days)
Hello
Please I have the following time series { 111110011111000000011000011111} in time interval of seconds.
I want to use the following conditions on the sequence. Assuming 1 = True and 0 = false
if false is < 3 seconds and are inbetween two "true periods" then it is translated as 1
if true is < 3 seconds they are translated into 0
The answer when the condition is applied is
11111111111100000000000011111
I will be grateful if anyone assist me in writing this code
Thanks in advance

Hi Walter
Yes the possibility of both is implemented. In the first instance you gave
the 11100111 because zeros is surrounded by 1 then the new sequence is 11111111 ( 11 is converted to 00)
For the second instance 11100111 because it is surrounded by zeros and less than 3 length it is converted to 11 (00 is converted to 11)
Hope it is clear Walter

a='111110011111000000011000011111';
a=strrep(a,'1001','111');
a=strrep(a,'101','111');
a=strrep(a,'010','000');
a=strrep(a,'0110','000');
